4. The decomposition reaction of a liquid reactant A is known to follow first order kinetics. When the reaction is carried out at 60C in a batch reactor, we find 70% of A being converted in 13 minutes. (a) What is the value of the rate constant for the reaction? Answer: 0.0926(min)17 (b) If the same reaction were to be carried out using the same initial concentration of A at a lower temperature of 40C, would the rate constant of the reaction be the same or different? (c) If the same reaction were to be carried out in a CSTR, what would the order of the reaction be? (d) Find the space time of the CSTR required to achieve the same reaction conversion of 70% at 60C ? Answer: 25.2min (e) If the same reaction was carried out in a 26 litre PFR with a volumetric flow rate of the reactant equal to 2 litre per minute at 60C, what conversion of the reactant would be reached at the end of Answer: 70% the PFR
